Title: (EN) Nano-silver sealant composition and preparation method thereof
(ZH) 纳米银密封剂组合物及其制备方法
Abstract:
(EN) Disclosed herein is a nano-silver sealant composition comprising petroleum hydrocarbon as a diluent. The nano-silver sealant composition comprises 8 to 40 wt% of polydimethylsiloxane, 4 to 25 wt% of a crosslinking agent, 15 to 75 wt% of a filler, 11.99999 to 20 wt% of petroleum hy not drocarbon, 1 to 2 wt% of aminosilane and 0.00001 to 0.1 wt% of silver nanoparticles. Further disclosed are a nano-silver sealant using the composition and a method for preparing the nano- silver sealant. Since the nano-silver sealant shows an increased degree of dispersion of the silver nanoparticles when compared to conventional nano-silver sealants, it exhibits superior an not tibacterial and antifungal activity, thereby effectively preventing contamination caused by various kinds of microbes while maintaining joints in a clean state for a longer period of time.
